SAFE.

SPECIFICATION forming part of Letters Patent No. 402, 590, dated May 7, 1889.

Application filed January 8, 1889.

To all whom it may concern:

Be it known that I, JOSEPH L. HALL, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Safes, of which the following is a specification.

My invention relates to safes; and the invention consists incertain novel features of construction, as hereinafter explained.

Figure 1 is a perspective View of the front portion of a safe, showing the door open. Fig. 2 is a face view, looking from the inside, of the front wall and door, partly in section. Figs. 3 and 4 are transverse sectional views of the front wall and door, taken on the line as m of Fig. 2. Fig. 5 is a similar view on the line y y of Fig. 2. Fig. 6 is a horizontal sectional view of the front wall with the door hung 011 the outside, and showing the movable rings detached.

This invention relates to that class of safes which have a circular door provided with a series of lateral projections which enter corsponding recesses in the jambs, and which, by turning the door after it is closed, engage with similar projections on the jambs to prevent the door from being pulled open; and one object of the invention is to so construct .and arrange the parts that when the door is closed and turned to position the recesses, both in the periphery of the door'and' in its surrounding jamb, shall be filled with solid metal, instead of leaving open spaces at those points, as has heretofore been customary. The means by which I accomplish this result are as follows: The body of the safe and its door are composed of a series of plates, more or less in number, five plates being represented in the present instance, though it is 0 obvious that more may be used,'if desired,

and that the plates may be of any thickness desired.

In the drawings, Aindicatesthe wall of the safe, and B the door, whichis made circular in form to fit a corresponding opening in the front wall, as shown in Figs. 1 and 2. The first, second, and fifth plates of the door, as numbered in Fig. 1, are made circular, while plate 4, which is next to the inner one, is pro Serial No. 295,792. (No model.)

vided with a series of lateral projections, b, of a dovetail form, as shown in Fig. 1, these projections Z) entering corresponding-shaped notches or recesses cut in plate 3 of the wall,- as clearly shown in Fig. 1. When the door is closed, the projections b on the door will pass beyond plate 3 of the wall, and then by turning the door bodily on its supporting-stud P, on which .it is journaled, as shown in Figs. 3 and 4, the projections Z) of the door will be moved around behind the projections h on plate 3 of the wall, thus holding the door secure against being opened until it is again turned, so as to bring the projections I) opposite the recesses Z. If left in this condition, it is obvious that when the door was closed and turned the spaces between the edges of the projections Z) on the door and also the recesses Z in the wall-plate would be unoccupied, thus forming a series of pockets or cavities, into which explosives could be inserted 7o by drilling holes or otherwise. To prevent this I out the opening in plate 4: of the wall enough larger than the others'to enable me to place therein a loose ring, E, (shown detached in Fig. 6 and in position in Figs. 1, 3,

4:, and 5,) this ring being provided with recesses Z, corresponding in shape and size with those. in plate 3, so that when made to register with those of plate3, as shown in Fig. 1, the projections 19 of the door will enter the recesses l of this ring E and fill them, and then as the door is turned the projections 12, occupying the same plane as the ring E, will of course carry the ring around with them as the door is turned in either direction, and by these means I fill up the spaces that otherwise would be left in the jamb or wall in the line of plate 4. I also place a similar loose ring, D, in the door, it being placed in the plane occupied by plate 3 of the door, and 0 being provided with lateral projections a of the same size and form as the projections b on the fixed plate 4, so as to register therewith, as shown in Figs. 1 and 6. When the door is closed, these projections a on ring D 5 will enter and fill the recesses Z in plate 3 of I the wall, and which of course will hold the ring D stationary while the door is being turned in either direction, thus preventing the leaving of any cavity in the plane of plate 3, as shown more clearly in Figs. 3, 4, and 5.

While for the purpose of more readily explaining this part of my invention I have shown and described the rings as being arranged or located in the line or planes of certain plates, and have indicated the plates by numerals both in the door and in the wall, it will of course be understood that they may be located differently, it only being necessary that the ring or rings in the one partshall be so located as that when the door is closed they shall occupy the same plane or be in line with the fixed plates which have the projections or recesses in 'the other part. So, too, while I have shown but one ring in each partthat is, one in the wall and one in the door, with but one set of engaging projections, 1), on the door and h on the jamb or wall,it is obvious that these may be duplicated or increased to any extent desired, either by using more plates or by providing more of the plates with engaging projections 11 and 72, all this, as well as the thickness of the plates, being a mere matter of choice or judgment on the part of the manufacturer.

In order to enable the door to be operated, it is hung upon a T-shaped stud, I, on which it is journaled, as shown in Figs. 3 and 4:, so it can readily be turned in either direction, and to enable the door to be swung in and out a bracket or arm, 0, having its inner end made T-shaped and provided with a journal at its extremities, is secured by boxes or bearings 0 to the inner face of the front wall, as shown in Figs. 1 and 2, this bracket or arm being bent or made with an elbow at its inner end, so as to enable the door to be swung back out of the way, as represented in Fig. 1, the outer end of said arm being bifurcated and journaled to the ends of the T-headed stud I, as shown in Figs. 1 and 2. By this construction I am enabled to hang the arm which support-s the door on the inside of the safe or vault, and at the same time support it so firmly as to prevent it from sagging, which, if it should occur, would render it difficult, if not impossible, to close it.

In Fig. 6 I have shown the door hung on the outside, in which case the supporting arm or bracket 0 will have its two arms made V- shaped or spread apart at the ends which are hinged to the wall, so as to give as firm a support as possible, the opposite end being made broad enough to have a hole in it to receive the bolt m, said bolt or stud being rigidly secured to the door and provided with a lever or handle, H, as shown in Figs. 3, 4, and 6, by which the door can be turned to fasten and unfasten it. Either method of hanging the door may be used, as preferred; but I prefer the plan shown in Figs. 1 and 2, as in that case the hinge or support cannot be got at by burglars, and it leaves the exterior of the safe perfectly smooth and without any projection, except a knob or handle for turning it.

In order to prevent the loose rings from being accidentally moved when the door is open and hold them in the proper position so their recesses and projections will register or be in line with those of the adjoining fixed plates, and which is necessary to enable the door to be closed, I provide one or more springstuds, g, as shown in Figs. 3 and 4:. These studs are set in holes in either the rings or the plates, (they being shown in both,) and have bearing against their rear ends or against an annular shoulder formed on them a small spiral spring, which is held in place by a thin screw-plug, e, which is inserted so as to be flush with the face of the plate or ring, as the case may be, the front end of the stud 9 being rounded and made to engage in a corresponding cavity in the face of the adjoining plate or ring, as shown. By this means the rings are held against accidental movement, with their projections and recesses in line with those of the adjoining plates, whereby the door can be closed at any time without waiting to adjust the rings, and yet leave the rings in a condition to be readily turned whenever necessary, it being understood, of course, that the cavity in which the rounded point of the stud engages is very shallow, just sufiicientto hold the ring against accidental movement by the swinging or j arring of the door.

It is obvious that by using a stiffer spring the pressure of the stud 9 against the plate or ring will be sufficient to hold the ring by its friction or pressure, in which case the cavity may be dispensed with, and also that a fiat friction-spring maybe applied either to the face or inner edge of the rings and be made to operate the same, these all being well-known mechanical equivalents.

The door may be locked in various ways; but I prefer-the plan shown in Fig. 2. This consists of a bolt, L, which projects through a hole in the inside plate, and also through a hole in the ring E, as shown in Figs. 3 and 4, its inner end projecting into a hole in the adjoining plate for greater security. When this bolt L is inserted in the hole in the ring E, as shown in Fig. 4, it will of course prevent the ring from being moved or turned around; and as the projections?) of the door rest in the recesses Z of the ring, it follows that the door is also held against being turned, and consequently cannot be opened. This locking-bolt L is shoved in by a spring and is withdrawn by an elbow-lever, n 0, the arm n being slotted and made to engage the bolt L, as shown in Figs. 2, 3, and 4, or in any equivalent manner, while its other arm, 0, is connected to a sliding rod or bar, R, having a weight, WV, attached, said rod being connected by intermediate hooked levers, t' and m, to a time-lock, T, as shown in Fig. 2, and as more fully described in my patent of February 26, 1889, No. 398,609. Any number of locking-bolts L may be used, they being connected by suitable means, so that all will be withdrawn simultaneously, as shown in said prior application. As shown in Fig. 1, the door and its jamb or seat in the wall is made with steps or oifsets, as is usual, and the door and Wallis also provided with an interlocking tenon and groove, as shown in Figs. 1, 3, 4:, 5, and 6.

By this construction I am enabled to construct a safe with a circular door having lateral projections arranged to enter through recesses in the jambs and engage behind similar projections on the jamb or wall of the safe, and at the same time fill the recesses in the door and in the jamb with solid metal, thereby avoiding the presence of any pockets or cavities for the reception of explosives.

Having thus described my invention, what I claim isr 1. In combination with the circular door B, provided with lateral projections b, the loose ring E, provided with correspondingly-shaped recesses located in the wall of the safe in line with the projections 19 of the door when the latter is closed, substantially as and for the purpose set forth.

2. In combination with the circular door B, 30 the'loose ring D, provided with lateral projections a, said ring being so located in the doorthat when the latter is closed the projections' a of said. ring shall occupy the recesses Z in the locking-plate of the wall, substantially as shown and described.

3. In combination with a safe and its door,

one or more loose rings, constructed as described, located in each of said parts, respectively, and arranged to operate as set forth, whereby the lateral recesses in the doorand its jamb are filled with solid metal when the door is closed.

4:. In combination with the circular door,

provided with lateral projections arranged to- JOSEPH L. HALL.
